Abstract

When mental disorders disrupt thought, emotion, and participation in life, what is often
lost is not only health, but belonging to existence itself. Within Spiritism, mental suffering is understood as spiritual dislocation extending beyond the individual psyche, involving discarnate influence and unresolved bonds across lives. However, spiritual practices that engage this dimension, such as mediumship, disobsession, magnetism, and instrumental transcommunication, remain largely excluded from academic and clinical frameworks. This work examines the inclusion of these practices as expressions of an ethics of belonging, offering individuals a way to remain within life when mental suffering erodes meaning, dignity, and place.
